Engineering Selection Recommendations

Direct Replacement Priority (Active Status):

The following parts are recommended as primary substitutes due to active product status and full electrical/mechanical compatibility:

T322E226K035AT (KEMET): Active status with ROHS3 compliance. ESR specified at 1.3 Ohm. Highest inventory availability (2818 Pcs). Identical physical dimensions to main part (0.280" Dia x 0.530" L).
173D226X9035YE3 (Vishay Sprague): Active status with ROHS3 compliance. Tape & Box packaging. Suitable for applications requiring RoHS3 certification.

Secondary Substitutes (Active Status, Non-Compliant RoHS):

173D226X9035YW (Vishay Sprague): Active status. Tape & Reel packaging. Slightly longer case (0.550" L vs. 0.530" L). Verify PCB layout clearance before selection.
T322E226K035AS (KEMET): Active status. Bulk packaging. ESR specified at 1.3 Ohm. Identical physical dimensions to main part.
173D226X9035Y (Vishay Sprague): Active status. Tape & Box packaging. Slightly longer case (0.550" L vs. 0.530" L). Verify PCB layout clearance before selection.

Compliance Considerations:

Parts with ROHS3 compliance (T322E226K035AT, 173D226X9035YE3) are preferred for new designs or applications subject to RoHS regulations. Non-compliant alternatives remain suitable for legacy system support and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can T322E226K035AT replace TAC226K035P07 directly?

A: Yes. T322E226K035AT maintains identical capacitance (22 µF), tolerance (±10%), voltage rating (35 V), mounting type (through hole), and package style (axial). Physical dimensions are identical (0.280" Dia x 0.530" L). Active product status ensures ongoing availability.

Q: What is the difference between 173D226X9035YW and 173D226X9035Y?

A: Both parts are electrically identical (22 µF, ±10%, 35 V, axial, through hole). The primary difference is packaging format: 173D226X9035YW is supplied in Tape & Reel format, while 173D226X9035Y is supplied in Tape & Box format. Physical case length differs slightly (0.550" L vs. standard 0.530" L). Verify PCB layout clearance for the longer case variant.

Q: Are ROHS3-compliant parts (T322E226K035AT, 173D226X9035YE3) electrically equivalent to the non-compliant main part?

A: Yes. RoHS compliance status reflects manufacturing process and material composition, not electrical performance. ROHS3-compliant substitutes maintain identical electrical specifications and are suitable for direct replacement in all applications.

Q: What does the ESR specification mean for KEMET parts?

A: ESR (Equivalent Series Resistance) of 1.3 Ohm is specified for T322E226K035AT and T322E226K035AS. This parameter indicates internal resistance and affects high-frequency performance. The specified ESR value is within acceptable limits for general-purpose tantalum capacitor applications.

Q: Can I use 173D226X9035YW if my PCB has limited space?

A: 173D226X9035YW has a case length of 0.550" L compared to the standard 0.530" L. Verify available PCB clearance before selection. If space is constrained, use T322E226K035AT or T322E226K035AS, which maintain the original 0.530" L dimension.

Q: Which substitute has the highest inventory availability?

A: T322E226K035AT (KEMET) has the highest inventory with 2818 Pcs in stock, followed by 173D226X9035Y (1029 Pcs) and 173D226X9035YW (1055 Pcs).

Q: Are all substitute parts through-hole axial components?

A: Yes. All listed substitutes maintain through-hole axial mounting configuration, ensuring mechanical compatibility with existing PCB designs without layout modifications.
